Fixed 10 mm riser for paving pedestals – ESSENTIEL Range – Jouplast

In order to have a solid and durable structure, ground preparation is necessary before laying slab on pedestal. Indeed, to enjoy your outdoor space in peace, it is necessary to have a flat and stable ground. Better still, this ground preparation guarantees durability over time. Conversely, unprepared ground can evolve and move depending on the weight and climatic conditions.

To keep your tiled terrace on pedestals for a long time, forget about laying a mortar screed! Preparing the ground for paving terrace pedestals is as simple as it is economical!

Here is what you need for the preparation:

• A cord
• Stakes
• A spirit level
• A shovel
• A tape measure
• A mason's box screed
• A geotextile film
• Gravel

4 steps are enough to prepare your ground to accommodate a tiled terrace on a pedestal:

1. Dig the ground for 15 cm;
2. Place a geotextile felt there to eradicate the growth of weeds and save you additional maintenance;
3. Fill the hole with a draining foundation by depositing a layer of 30/60 or 40/80 crushed stone. If the surface obtained still has some defects, it is important to make a laying bed with quarry sand or crushed sand type 0/4. Indeed, this will facilitate the installation of the 10 mm studs;
4. Compact and make sure everything is level.

However, if your ground is concrete or an old terrace structure, the preliminary work will be minimal. All you have to do is clean the existing surface and check the flatness of the floor, which is an essential criterion for a perfect terrace.
